Application filed July 89, 1813. Serial No. 781.806.

Be it known that I, Ennn JAGuKBERG, a subject or the German Emperor. and residing at 107 llinnnelgeisterstrasse, Dusseldorf, Germany, hare invented certain new and useful Improvements in Paper-Feeding Apparatus, of which the following is a specifieation.

The present invention relates to an arangeinent for relnering the cardboard sheets from the pile in cardboard box making machines and the like. Hither-t0 the sheets were removed singly from the pile by a slide pushing hem through a a ary shit. the Width at which corresponded to the tlllClUiGSa 0f the sheet These arnngeniente, limreixi-r. Work properly only as long as the cardhnards in the pile are straight and level. \i'hen these wrdheards arecurved m: warped. and thie err-tire very frequently the edge ml the farrinest sheet h: be removed will not meet the sleuand the sheet hitilQlt trequentl trrunpled 1p lrv' the advancing slide. This trouble obviated h the present inrentinn, \1'ltltl1 eunsists in that the Slot, through whit-h the sheets are to pass, is :30 displaeallle, thatit will aideniatieally adjust itself exactly under the edge of the l ra-sums; sheet to l ad1 aneed.

tell? The present invention is exemplified in the accompanying dra wing.

Figure l is a longitudinal eeetiun and Fig. 2 is a plan of the arrangement.

The piled eardtmard sheete (z are preseed by the am 7) z "'t the vertically reriprtr cable slide 0. 'l he slide 2 llitrYQ-b in the guide (Z and has a tongue f, which; on the slid-1'- destendiug. will NQLtlL n the upper edge of the 'fOItlliuSi .s iret and pres: tl1elatterdown- Ward oil the pile. Thin tongue ma be adusted by 1110:1115 at a siren and will the upper edge oi' the sliiifrti will hear again: the slide, so that it peaeihle for the hil 1 t0 remore alsu curved or \i'arped sheets. lielow the SllLt'iS are 'l'mt'ed an'aimt a narrmv, fiat spring /1 whit-h is atavhed to a wide lierizentally rer-i y wahle plunger 5. The llat spring is arr aged dram-ire tn 1: centrally dispneeil tl.i lmljl'e A. whit-h is like WlS attached 11 111 9): in ,eueh a inanhirin bet-Ween thrn1- selves a na l-run .4111. m which i narrower in the middle and wider at the ends. The plunger is guided with the shmilder 7b in fepies the top of the machine and is drav; by means of a spring 0 toward the ram 5. The upper end of the flat spring 71 is slightly curved and supported by a SClGW g), bf, means of which the Width of the slot m may be aried according; to the thickness 0!: the cardboard sheets. The she. are for the rain with their lower e0 5 againet the fiat spring 74, and the latter then recedes under their pressure. tag-:1; her with the plunger '2' at the same time tightening the wring a. The loirer edge of the 'ffilGlUOwi sheet will therefore almrys he exaetly ever tl: hlot m, that this sheet Can he pushed dmrnward by 1n ans of the trngue f.

As the width or the slot in is onlg. i1 111iddle portion as narrow as the thicl; of the sheet. and this portion short, ails 0 \ride and curred sheets can he removed, as

the wide slots at the side alhia at the sheets 1 msing through. The a pre vlded 111 the slots r at the Sines aim win v rging below, and the ledgra will then straighten the sheets.
